The megalodon; a fearsome shark, roamed the oceans, scaring (and eating) everyone in its path. And this was for a long time after the dinosaurs were wiped out by the infamous Great Killer Meteorite. We know that it was the largest and most aggressive predator that ever lived, as well as the largest shark. It was the king of the seas, and it swam freely throughout the ocean. But then, about 2.5 million years ago, the last of its species disappeared from Earth forever, leaving only their enormous teeth for modern archaeologists to see. So why did megalodons go extinct? At first, scientists thought that around the time the megalodon went extinct, there was a massive underwater extinction event that occurred. They believe that a supernova exploded about 150 light-years from Earth, and its cosmic radiation reached our planet, changing its climate. But in 2019, a group of researchers discovered something strange: the fossils left behind by these monstrous sharks [subscribe] were from an earlier period. This could mean that they went extinct before the supernova explosion. So a new explanation had to be found, and it came from an unexpected source… #BrightAway Goblin Shark, Pengo: By Wikimedia, CC BY-SA 3.0 https://creativecommons.org/licenses/..., https://commons.wikimedia.org/w/index...
